Concentrations and mortality due to short- and long-term exposure to PM 2.5 in a megacity of Iran (2014–2019)

摘要: The present study aimed to survey the spatial and temporal trends of ambient concentration PM2.5 estimate mortality attributed short- long-term exposure in Isfahan from March 2014 2019 using AirQ+ software. hourly concentrations were obtained Department Environment Air Quality Monitoring Center. Then, 24-h mean for each station was calculated Excel According results, annual 2014–2019 29.9–50.9 μg/m3, approximately 3–5 times higher than WHO guideline (10 μg/m3). data showed that people almost 58% 96% days a year exposed daily guideline. cold months such as October, November, December January those other months. zoning urban areas highest related northern, northwestern, southern central city. On average, 2019, number deaths due natural mortality, lung cancer (LC), chronic obstructive pulmonary disease (COPD), ischemic heart (IHD) stroke associated with 948, 16, 18, 281 60, respectively. estimated on 14.29% total 17.2% 15.54% 17.12% 14.94% mortalities PM2.5. So provincial managers politicians must adopt appropriate strategies control air pollution reduce attributable health effects economic losses.
